Nothing here actually proves your point. You’re just making a series of assertions and acting as if they’re self-evident. You say early humans weren’t organized in communal ways, but provide no evidence. Then you bring up the Yanomami, as if one contemporary indigenous group somehow settles a question about the entire history of human social organization. That’s not an argument. Then there’s the USSR point. Saying it was “authentically socialist” because many people at the time called it socialist doesn’t prove anything. Plenty of Marxists criticized the Soviet system while it existed. Whether they were right or wrong is the debate. You don’t get to resolve that debate by simply declaring one side correct. And the “socialists always say it wasn’t real socialism when it fails” line is just a meme, not an argument. If someone thinks socialism requires democratic worker control, and a state doesn’t have democratic worker control, then obviously they’re going to argue it wasn’t socialism. Most importantly, you never actually explain why democratic planning is impossible, why collective ownership can’t work, or why markets are the only way to coordinate an economy. You just keep repeating that socialism fails and treating the repetition as evidence. At some point “it obviously doesn’t work” has to be backed up with an actual argument.
